I had the privilege of working with Roger from time to time over the years as part of the Solaris Kernel group (which I am still currently part of). I also had a rare opportunity for a more personal conversation with him during a trip to Manchester in 2015 where he regaled me with tales of his home and life. Roger's greatest gift was "telling it like it is", but always in a way that you knew was truthful, well-meaning, and not in a way purely for the sake of offence. He always cut right to the heart of the matter, and of course his distinguished Carolinian accent helped soften the blow to your ego. The last time I had the opportunity to collaborate with him was on a fairly minor addition to Solaris libc I was making -- pthread_getattr_np, in January of this year (2016). Let me tell you from experience that the greatest praise any engineer could receive and the greatest sign of success for their projects was Roger's endorsement. I miss him greatly, and UNIX and the world feels lessened by his passing.
